It explores critical astronomical data, including orbital durations such as the 27.3-day sidereal month and the 29.5-day synodic month, which defines the complete cycle as seen from Earth. The content addresses common inquiries regarding planetary alignment, specifically investigating whether the Earth blocks moonlight, supported by visual diagrams illustrating the 5.14-degree orbital inclination. Through clear labeling of lunar stages like the New Moon and Waxing Crescent, the material serves as an accessible guide for understanding the geometric relationship between the Earth, Moon, and Sun, ensuring a fundamental grasp of celestial movements and the resulting visual changes in lunar illumination throughout the year.",{"@graph":14,"@context":73},[15,34,56],{"@type":16,"itemListElement":17},"BreadcrumbList",[18,23,27,31],{"item":19,"name":20,"@type":21,"position":22},"https://docshare.wps.com","Home","ListItem",1,{"item":24,"name":25,"@type":21,"position":26},"https://docshare.wps.com/template/","Template",2,{"item":28,"name":29,"@type":21,"position":30},"https://docshare.wps.com/template/general/","General",3,{"item":32,"name":10,"@type":21,"position":33},"https://docshare.wps.com/template/phases-of-the-moon-an-astronomical-overview/564207/",4,{"url":32,"name":10,"@type":35,"image":36,"author":41,"headline":10,"publisher":44,"fileFormat":47,"inLanguage":8,"description":12,"dateModified":48,"datePublished":49,"encodingFormat":47,"isAccessibleForFree":50,"interactionStatistic":51},"DigitalDocument",{"url":37,"@type":38,"width":39,"height":40},"https://docshare.wps.com/thumbnails/phases-of-the-moon-an-astronomical-overview/564207.png","ImageObject",442,249,{"name":42,"@type":43},"นรินทร์","Person",{"url":19,"name":45,"@type":46},"DocShare","Organization","application/pdf","2026-10-23","2026-10-12",true,{"@type":52,"interactionType":53,"userInteractionCount":55},"InteractionCounter",{"@type":54},"ViewAction",10,{"@type":57,"mainEntity":58},"FAQPage",[59,65,69],{"name":60,"@type":61,"acceptedAnswer":62},"What is the difference between the 27.3-day and 29.5-day lunar periods?","Question",{"text":63,"@type":64},"The 27.3-day period is the sidereal month, representing the time it takes for the Moon to orbit the Earth relative to distant stars, while the 29.5-day period is the synodic month, which is the time required for the Moon to return to the same phase as seen from Earth.","Answer",{"name":66,"@type":61,"acceptedAnswer":67},"Why does the Moon not always pass through the Earth's shadow?",{"text":68,"@type":64},"The Moon's orbit is tilted at an inclination of 5.14 degrees relative to the Earth's orbit around the Sun, which prevents the Earth from blocking the Sun's light to the Moon during every orbit.",{"name":70,"@type":61,"acceptedAnswer":71},"What are the primary phases of the Moon depicted in the document?",{"text":72,"@type":64},"The document identifies key phases including the New Moon and the Waxing Crescent as part of the ongoing lunar cycle.","https://schema.org",{"og:url":32,"og:type":75,"og:title":10,"og:site_name":45,"og:description":12},"article",{"robots":77,"canonical":32},"index,follow",{"doc_id":79,"site_id":7},564207,1792012799,{"code":4,"msg":82,"data":83},"success",[84,89,94,99,104,109,114,119,124],{"id":85,"doc_module":22,"doc_module_name":25,"category_name":86,"show_sort_weight":87,"slug":88},11,"Presentations",90,"presentations",{"id":90,"doc_module":22,"doc_module_name":25,"category_name":91,"show_sort_weight":92,"slug":93},12,"Resumes",80,"resumes",{"id":95,"doc_module":22,"doc_module_name":25,"category_name":96,"show_sort_weight":97,"slug":98},14,"Invoices",70,"invoices",{"id":100,"doc_module":22,"doc_module_name":25,"category_name":101,"show_sort_weight":102,"slug":103},15,"Posters",60,"posters",{"id":105,"doc_module":22,"doc_module_name":25,"category_name":106,"show_sort_weight":107,"slug":108},16,"Social Media",50,"social-media",{"id":110,"doc_module":22,"doc_module_name":25,"category_name":111,"show_sort_weight":112,"slug":113},17,"Forms",40,"forms",{"id":115,"doc_module":22,"doc_module_name":25,"category_name":116,"show_sort_weight":117,"slug":118},18,"Letters",30,"letters",{"id":120,"doc_module":22,"doc_module_name":25,"category_name":121,"show_sort_weight":122,"slug":123},21,"Paper Templates",5,"papers-templates",{"id":125,"doc_module":22,"doc_module_name":25,"category_name":29,"show_sort_weight":4,"slug":126},158,"general-158",{"code":4,"msg":82,"data":128},{"doc_id":79,"user_id":129,"nickname":42,"user_avatar":130,"doc_module":22,"category_id":125,"category_name":29,"doc_title":10,"doc_description":12,"doc_content":131,"file_id":132,"file_url":133,"file_type":134,"file_size":135,"view_count":55,"is_deleted":4,"is_public":22,"is_downloadable":22,"audit_status":22,"page_count":110,"language":136,"language_code":8,"site_id":7,"html_lang":8,"table_of_contents":137,"faqs":138,"seo_title":139,"seo_description":12,"update_tm":140,"read_time":141},2336475104957,"https://ap-avatar.wpscdn.com/avatar/22000c4c6bd8a5076e1?x-image-process=image/resize,m_fixed,w_180,h_180&k=1787554080175789136","Phases ofthe Moon  \n1 year  \n27.3 days  \n29.5 days  \nWouldn’t the Earth Block Moonlight?
